On the other hand, the connecting pin 50 is inserted into a downwardly tapering receiving opening 52 of the door closer 35 by means of a likewise tapering pin 76, a coaxial collar 53 arranged in the center of the connecting pin 50 both on the end face of the head 49 and on the surface of the Door closer 35 is present.

Über dem Kopf 49 des Verbindungsarmes 44 ist der Abdeckarm 45 lösbar angeordnet. Die dem Aufnahmeraum 42 zugewandte Oberfläche des Abdeckarms 45 hat ihre Funktion als Abrollfläche 54 für den als Niederhalter für den Verbindungsarm 44 ausgebildeten Rollenhalter 46, dessen Rolle 55 um eine parallel zum Boden verlaufende Achse 56 frei drehbar angeordnet ist. Unterhalb der Achse 56 in einem Abstand zu dieser, parallel zum Boden verlaufend, weist der Rollenhalter 46 eine durchgehende im Querschnitt kreisabschnittförmige Ausnehmung 57 auf, in die ein Bolzen 58 gleichen Querschnitts eingesteckt ist.The cover arm 45 is detachably arranged above the head 49 of the connecting arm 44. The surface of the cover arm 45 facing the receiving space 42 has its function as a rolling surface 54 for the roll holder 46 designed as a hold-down device for the connecting arm 44, the roll 55 of which is freely rotatable about an axis 56 running parallel to the floor. Below the axis 56 at a distance from it, running parallel to the floor, the roller holder 46 has a continuous recess 57 with a circular cross section, into which a bolt 58 of the same cross section is inserted.

Der Bolzen 58 kann mit einer Madenschraube 59 gegen ungewolltes Herausziehen gesichert sein und ist zur besseren Handhabung mit einem länglichen Handgriff 60 versehen.The bolt 58 can be secured with a grub screw 59 against unwanted pulling out and is provided with an elongated handle 60 for better handling.

Die beiden Gehäusehälften des Adapters 37 weisen zwei miteinander fluchtende Langlöcher 61 auf, welche die Gehäusehälften von ihrer Oberfläche her durchdringen, So ist es möglich, den Bolzen 58 durch ein Langloch 61 und die kreisabschnittförmige Ausnehmung 57 durchzustecken, so daß die Stirnfläche 67 des Bolzens 58 mit der Oberfläche der anderen Gehäusehälfte bündig abschließt. Das Langloch 61 dient somit als Zwangsführung für den Bolzen 58, wenn dieser mittels Handgriff 60 den Rollenhalter 46 aus beispielsweise einer in etwa senkrechten Lage in eine in etwa waagerechte Lage bringen soll oder umgekehrt. Der Bewegungsablauf des Rollenhalters 46 im Aufnahmeraum 42 ist hiermit genau vorgegeben.The two housing halves of the adapter 37 have two aligned elongated holes 61, which the Penetrate the housing halves from their surface, so it is possible to push the bolt 58 through an elongated hole 61 and the circular recess 57 so that the end face 67 of the bolt 58 is flush with the surface of the other housing half. The elongated hole 61 thus serves as a positive guide for the bolt 58 when it is to use the handle 60 to bring the roller holder 46 from, for example, an approximately vertical position to an approximately horizontal position, or vice versa. The sequence of movements of the roller holder 46 in the receiving space 42 is hereby precisely specified.

Wird der Rollenhalter 46 von seiner in etwa senkrechten Lage in die waagerechte Lage gebracht, so zieht eine zwischen Abdeckarm 45 und Verbindungsarm 44 angelenkte Rückholfeder 62 den Verbindungsarm 44 in den Aufnahmeraum 42 vollständig zurück. Der Rollenhalter 46 liegt dabei in seiner Endlage etwa auf der Hälfte seiner Länge in einer über dem Kopf 49 einstückig mit dem Verbindungsarm 44 ausgebildeten Aufnahmetasche 63.If the roller holder 46 is brought from its approximately vertical position into the horizontal position, a return spring 62 articulated between the cover arm 45 and the connecting arm 44 completely pulls the connecting arm 44 back into the receiving space 42. In its end position, the roll holder 46 lies approximately at half its length in a receiving pocket 63 formed integrally with the connecting arm 44 above the head 49.

Der Adapter 37 kann sowohl von der einen als auch der anderen Stirnseite bedient werden. Hierzu wird der Rollenhalter 46 mittels des einen Hebel 64 bildenden Bolzen 58 und Handgriff 60 in die waagerechte Lage bewegt (s.Fig.3), so daß durch ein Sichtloch 65 in der oberen Längstirnseite des Adapters 37 die Madenschraube 59 mit Hilfe eines Inbusschlüssels 66 o.dgl. gelöst werden kann. Der Hebel 64 wird aus der kreisabschnittförmigen Ausnehmung 57 herausgezogen und von der Gegenseite wieder eingesteckt. Hierbei schließen die Stirnfläche 62 des Bolzens 58 mit der Oberfläche der entsprechenden Gehäusehälfte des Adapters 37 ab. Die Madenschraube 59 wird mit dem Inbusschlüssel 66 durch das Sichtloch 65 hindurch wieder fest angezogen. So ist der Adapter 37 auch von der Gegenseite her zu betätigen.The adapter 37 can be operated from one end as well as from the other. For this purpose, the roller holder 46 is moved into the horizontal position by means of the bolt 58 and handle 60 forming a lever 64 (see FIG. 3), so that the grub screw 59 with the aid of an Allen key 66 through a viewing hole 65 in the upper longitudinal end face of the adapter 37 or the like can be solved. The lever 64 is pulled out of the circular-section-shaped recess 57 and inserted again from the opposite side. Here, the end face 62 of the bolt 58 is flush with the surface of the corresponding housing half of the adapter 37. The grub screw 59 is tightened again with the Allen key 66 through the viewing hole 65. Thus, the adapter 37 can also be operated from the opposite side.

Der erfindungsgemäße Adapter ermöglicht bei ein- und derselben Tür sowohl den Einsatz als Schiebetür als auch den Einsatz als Schwenk- bzw. Pendeltür, ohne umständliche und zeitraubende Montage- und Umrüstarbeiten. Die Umstellung von Pendeln auf Schieben erfolgt wie nachstehend:
Auf der Schloßseite wird in der oberen Ecke mittels eines Hakenfallenschlossen (nicht dargestellt) die Verbindung des Türflügels mit der Schiebekonstruktion hergestellt.The adapter according to the invention enables the same door to be used both as a sliding door and as a swinging or swinging door, without cumbersome and time-consuming assembly and conversion work. The switch from pendulums to pushers is as follows:
On the lock side, the door leaf is connected to the sliding construction in the upper corner by means of a hook latch (not shown).

Der Türflügel wird vom Türschließer 35 gelöst, indem der Hebel 64 vom unteren in den oberen Endpunkt bewegt wird. Beide Endpunkte sind dabei durch die Zwangsführung des Bolzens 58 im Langloch 61 in der der Einsteck-seite jeweils gegenüberliegenden Seite vorgegeben. Dabei bewegt sich die Rolle 55 des Rollenhalters 46 über die Abrollfläche 54 hinwegt zur Bandseite der Tür hin. Am Anfang dieser Bewegung wirkt das untere Ende des Rollenhalters 46 so auf den Zapfen 51 ein, daß dieser den Verbindungsbolzen 50 nach unten in die Aufnahmeöffnung 52 des Türschließers 47 drückt. Es wird somit ein Herausziehen des Verbindungsbolzens 50 aus der Aufnahmeöffnung 52 heraus vermieden, da diese Bewegung dem Bestreben der Rückholfeder 62, den Verbin-dungsarm 44 in den Aufnahmeraum 42 zurückzuziehen, entgegenwirkt. Analog der weiteren Bewegung der Rolle 55 zur Bandseite der Tür hin zieht die Rückholfeder 62 den Verbindungsarm 44 immer weiter nach oben: Der Kopf 49 hebt sich vom Verbindungsbolzen 50 und verläßt durch eine in einer den Aufnahmeraum 68 im Boden 34 für den Türschließer 35 abdeckenden Abdeckplatte 69 den Aufnahmeraum 68 und wird schließlich soweit in den Aufnahmeraum 42 hineingezogen, daß dieser den Verbindungsarm 44 vollständig aufnimmt. Der Rollenhalter 46 hat nun eine in etwa waagerechte Stellung zum Boden 34 eingenommen. Die Verbindung Türflügel-Türschließer 35 ist gelöst.The door leaf is released from the door closer 35 by moving the lever 64 from the lower to the upper end point. Both end points are predetermined by the positive guidance of the bolt 58 in the elongated hole 61 in the side opposite the insertion side. The roller 55 of the roller holder 46 moves over the rolling surface 54 toward the hinge side of the door. At the beginning of this movement, the lower end of the roller holder 46 acts on the pin 51 such that it presses the connecting bolt 50 downward into the receiving opening 52 of the door closer 47. Pulling out of the connecting bolt 50 out of the receiving opening 52 is thus avoided, since this movement counteracts the efforts of the return spring 62 to pull the connecting arm 44 back into the receiving space 42. Analogous to the further movement of the roller 55 towards the hinge side of the door, the return spring 62 pulls the connecting arm 44 ever further upward: the head 49 rises from the connecting bolt 50 and leaves the receiving space 68 in the floor in one 34 for the door closer 35 covering cover plate 69, the receiving space 68 and is finally drawn into the receiving space 42 to the extent that it completely receives the connecting arm 44. The roll holder 46 has now assumed an approximately horizontal position with respect to the floor 34. The connection door leaf door closer 35 is released.

Der untere Teil 70 der Feststelleinrichtung 31 wird von der Schiene 26 gelöst und die Funktion des Pendelns der Tür ist in eine des Schiebens umgesetzt worden.The lower part 70 of the locking device 31 is released from the rail 26 and the function of swinging the door has been converted into one of sliding.

Das Umstellen von Schieben auf Pendeln erfolgt analog der vorbeschriebenen drei Schritte im umgekehrter Reihenfolge.Switching from pushing to commuting takes place in the reverse order of the three steps described above.

Bei einem weiteren Ausführungsbeispiel des Adapters gemäß Fig.5 weist ein Verbindungsarm 71 an seinem der Achse 43 abgewandten Ende einen mit z.B. zwei im Querschnitt kreiszylindrischen Verbindungszapfen 72 versehenen Kopf 73 auf. Die Achse der beiden Verbindungszapfen 72, die sowohl zylindrisch als auch konisch zulaufend ausgebildet sein können, steht senkrecht zu der in der Schwenkstellung zum Boden 34 hin zugewandten und parallel verlaufenden Stirnfläche des Kopfes 73.In a further embodiment of the adapter according to FIG. 5, a connecting arm 71 has at its end facing away from the axis 43 one with e.g. two head 73 provided with a circular cylindrical connecting pin 72 in cross section. The axis of the two connecting pins 72, which can be designed to be cylindrical as well as tapering, is perpendicular to the parallel end face of the head 73 that faces the floor 34 in the pivoted position.

Dabei greifen die Verbindungszapfen 72 in Bohrungen 74 eines Verbindungsbolzens 75 ein, der die Schiebetür 10 mit dem Türschließer 35 verbindet. Hierbei hat die Abdeckplatte 69 eine Durchtrittsöffnung 77 für den Verbindungsbolzen 75; die obere Stirnfläche des Verbindungsbolzens 75 und die Oberfläche der Abdeckplatte 69 liegen auf einer Höhe.The connecting pins 72 engage in bores 74 of a connecting bolt 75, which connects the sliding door 10 to the door closer 35. Here, the cover plate 69 has a passage opening 77 for the connecting bolt 75; the upper end face of the connecting bolt 75 and the surface of the cover plate 69 are at one level.

Der Verbindungsbolzen 75 greift mit seinem als konisch zulaufender Zapfen 76 ausgebildeten, dem Boden 34 zugewandten Bereich in die Aufnahmeöffnung 52 des Türschließers 35 ein.The connecting pin 75 engages with its area, which is designed as a tapered pin 76 and faces the floor 34, into the receiving opening 52 of the door closer 35.

Beide Ausführungen haben den Vorteil, daß bei Schiebestellung der Schiebetür 10 - d.h. der Verbindungsarm 44 bzw. 71 ist von der ückholfeder 62 vollständig in den Aufnahmeraum 42 des Adapters hineingezogen - im Bereich der den Aufnahmeraum 68 für den Türschließer 35 verdeckenden Abdeckplatte 69, keine über die Oberfläche der Abdeckplatte 69 hinausragenden Bauteile vorhanden sind, da die Oberfläche der Abdeckplatte 69 und die obere Stirnfläche des Verbindungsbolzens 50 bzw. 75 auf einer Höhe liegen. Eine Stolper- und somit Verletzungsgefahr wird also für diesen Bereich passierende Personen o.dgl. vermieden.Both versions have the advantage that when the sliding door 10 is in the sliding position - i.e. the connecting arm 44 or 71 is completely drawn into the receiving space 42 of the adapter by the return spring 62 - in the region of the cover plate 69 covering the receiving space 68 for the door closer 35, there are no components projecting beyond the surface of the cover plate 69, since the surface of the Cover plate 69 and the upper end face of the connecting bolt 50 and 75 are at one level. A stumbling and thus risk of injury is or the like for people passing through this area. avoided.

Die Rückholfeder 62 ist dazu an zwei sich in einem bestimmten Abstand gegenüberliegenden Haltestegen 62a, 62b einerseits an der Abdeckplatte 69 und andererseit an dem Verbindungsarm 44 angelenkt.For this purpose, the return spring 62 is articulated on two holding webs 62a, 62b located opposite one another at a certain distance on the one hand on the cover plate 69 and on the other hand on the connecting arm 44.

Die Ausführung gemäß Fig. 5 hat außerdem noch den Vorteil, daß bei Schwenkstellung der Schiebetür 10 der Kopf 73 den Verbindungsbolzen 75 nicht umgibt und somit bei der Schiebestellung der Tür die Durchtrittsöffnung 77 der Abdeckplatte 69 nur den Verbin-dungsbolzen 75 umgibt. So ergibt sich bei eingezogenem Verbindungsarm 71 ein sehr kleiner, den Verbindungsbolzen 71 umgebender Spalt, der beim Ausführungsbeispiel in Fig.4 um die Wandstärke des Kopfes 49 größer ist.5 also has the advantage that, when the sliding door 10 is pivoted, the head 73 does not surround the connecting bolt 75 and thus the passage opening 77 of the cover plate 69 only surrounds the connecting bolt 75 when the door is in the sliding position. Thus, when the connecting arm 71 is drawn in, there is a very small gap surrounding the connecting bolt 71, which is larger in the exemplary embodiment in FIG. 4 by the wall thickness of the head 49.

Gemäß den Ausführungsbeispielen werden hiermit größere Ausnehmungen im Bereich der Abdeckplatte 69 und so eine weitere Stolper- und Verletzungsgefahr für die diesen Bereich passierende Personen o.dgl. vermieden.According to the exemplary embodiments, larger recesses in the area of the cover plate 69 and thus a further risk of stumbling and injury for the people passing through this area or the like. avoided.
